Application filed June 14,

This invention relates to stoves and has special reference to the stoves of that type in which the stove proper is enclosed within a casing, the walls of which are spaced from the walls of the stove propeiI to obtain a confined space in which the air is heated.

An object of the invention is to' .provide novel means for controlling` the admission of air into the lower end of the casino` at the front of the` stove and comprising a ninged plate or door adapted for movement-from open position in which air is freely admitted into the space in front of the stove to closed positionr when it isv desired to remove the ashes or products of combustion from the stove. f

Another object of theinvention is to provide a spring actuator for the'door or plate that is movable as aforesaid arranged in a relationship so that the power or resiliency of said actuator is utilized to hold the door' or plate in closed position and also in open position, but which actuator; will yield readily to permit movement of the door from either position to the other.v

Another object of the invention is yto provide an'improvement of the character inentioiied and asherein shown in a stove of the type disclosed in my co-pending 'application file-d June 6, 1928, Serial No. 233,135;

Other objects will appear from the following description, reference being made to the drawing in which Fig. 1 is aplan view of the invention embodied in a stove'of the typ-e'mentioned.

Fig. 2 is a lateral 4side or end elevation, the supporting frame for thel stove proper and a part of the casing lbeing in vertical section from front to rear. l p

Fig. 3 is an enlarged vertical sectional view of the device.

Fig. 4 is a sectional view of the rigid stove supporting the support p the admission of air to the stove casino' "'b My invention is embodied, in a Iheating frame showing` in end elevation stove device comprising a rigid .lower 'end frame made of an angle bar'having a horizontal flange 1 extending the. lower edge of `a vert-ic number of angle their horizontal i of the horizontal flanges 1 at the ends of the frame and secured theretoby bolts 4. Plates Y al flange 2. A bars 3 have .the ends of forming the .walls of a casingfor enclosfor thehinged door controlling p ylarge openings 23 therethrough inwardly from' p the front of the stove proper.

flanges seated upon the endsl 192s. serial No. 385,244.

to by'screws 9. Access is obtained tothe inside of the ash .chamber 10 of the stove proper through a hinged door 11 which-'may be opened to. permit insert-ion and withdrawalv of an ash pan or withdrawal of other contents of the ash chamber. The stoveV proper isvspaced from all of the walls 5 `of the casing and the lower end fraaie isopen so that air may freely 'enter vthe ycasing around and about the stove. The front casing wall 5. has a door opening 12 through which access Vmay be had to the stove proper and to the ash compartment thereof. Below the door opening 12 av bar y13 is secured within the rrigidsupporting This bar 13 extends rearwardly'and has a itiange or bead 13 along the upperside of its rear edgel which extends ander a flange or apron 19 extending downwardly' from the lugs and the flange 1 of the front edgefof the `base 6 and provided with a -I longitudinal horizontal shoulder 20.

Arms 21 kareformed integral with the ends .of the bar 13 and the rear ends of said armsv engage upon the shoulders 2 0. Thus, thebar 13 is strengthened and braced by engagement with parts of the stove proper. Webs 22 are formed integral with the bar 13 thelarms 21 and close the space' between 4 said parts "at the ends of said bar.' The rearwardly eX- ytending portion of the bar 13 has one or more for the `passageof air into the stove enclosing casing at i v It is desirable to provide means forlclosino l p n the openings 23 when Yashes v'are `being reniovedfroin the ash receptacle 10. For this purpose there is provided a door'or plate 24 havingfalinedpivot projections 25 on its ends Y' lio `1s 1n its down or closed `with an engageable handle i opening the same.

engaged by hinge retaining clips 26 attached to the bar 13 by bolts 27. These pivot pro jections 25 are near the front edge of the door or plate 24 and permit swinging movement oit said door or plate from position in which its rear edge seats upon the bar 13 in front of the flange or bead 18 to position in which said door or plate extends. upwardly. When the door or plate 24 is in itsupper position the openings 23 are open and permit free passage of air into the casing at the front of the stove proper. And when the door or plate 24 is in tslower position it will catch and retain any ashes or particles dropping from the ash pan being removed from the ash chamber 10 and prevent such ashes or particles from dropping to the loorof the roomin which the stove is contained. Theseashesor particles may be readily removed by sweeping or y brushing.

The bar l13 has a longitudinal bead or flange `28 in front of the openings 23. The front edge of the door or plate 24 has a shouldeiI 29 designed and adapted to abut against the flange or bead 28 when said door or plate is in its open position and thusprevent movement of said door or plate beyond its intended open position. Y f i A coil spring 30 has one end abutt-ing against the rear wall of one ol the openings 23 and su ported by a lug 31, and the opposite end a utting against the rear or under side of the door orplate 24 and retained in position by a lug 32. The relationship of the parts is such that when the door or plate 24 position the spring door or plate from such when the door or plate 30wi11 not move said closed position. AAnd is started in a movement toward open position thespring 30y will exceed its power Vto actuate said dooror plate through its final movements towardopen position as soon as the door or late passes a dead center line between the pivots 25 and the inner end of the spring 30.

The door or plate 24 is preferably provided 33 to facilitate From the foregoing thenature and principle of the invention must be apparent, it being` understood that the door or plate 24 is open when maximum heat-ing service is desired, and may be kept closed when less than maximum heating service is needed and may `also be closed to prevent dropping of ashes or particles onto the fioor during removal of the ashes from the ash receptacle.

The inventionmay be varied in numerous respects without departure from the nature and principle thereof. y

I do not restrict myself unessentially, but

what I claim anddesire to secure by Letters trolling'the rising of air through said fraaie at the front of said stove, and an actuator for moving ,aid door through itsiinal movements toward open position. Y i
